Plasticity of Till Materials

Plasticity of Till Materials

Plasticity of Till Materials

(OP)
The glacial till showed some cohesion during handling at site with a natural moisture content of about 9%.

When an atterberg limit test was performed the result showed zero,suggesting that the soil is non-plastic.

Could a cohesive soil show a PL of zero?  Thank you.

RE: Plasticity of Till Materials

I guess you mean the Plasticity Index was zero.

Till often has fines that are essentially rock flour.  Such well-graded materials to such fine size can show "cohesion" that may not hold up over time, being mostly related to capillarity.

Yes the actual question was:
"Could a cohesive soil show a PI of zero?"  and could a liquid limit test be carried out for these tests?
